TMA wire: Definition, Uses, and Clinical Overview
TMA wire is an orthodontic archwire made from a titanium–molybdenum alloy (often called “beta-titanium”). It is used in braces to guide tooth movement by delivering controlled, elastic forces through brackets and tubes. Clinicians often choose TMA wire when they want a wire that can be bent and customized more than some other wire types. You may hear it mentioned during mid-treatment adjustments, space closure, or detailed finishing steps.
